Esto es lo más sincero que he oído en mucho tiempo:

Today and spent more than 2 hours with the two Sony reps there and the 75inch ZD9. I pre-ordered the 75 inch from TPS with a 10% discount in late July so was keen to get a "preview" before the set arrives.

One rep had a USB so I watched a variety of content in 4K HDR, HD and SD.

My own observations are as follows (and don't attack me for them, this is just what my eyes saw!)

The TV's peak brightness really hits you in HDR scenes.
The colours are rich (I watched in Cinema Pro).
Yes, there is blooming, but it is faint. I noticed it on the Sony logo against the black backdrop as well as whenever there was white text against the black screen.
It produces very deep blacks with great shadow detail that I haven't seen on any TV.

However, I am cancelling my pre-order for it.

It's motion handling is not great. It was a bit embarrassing really as it was the first thing I noticed - movement in the Las Vegas scene on the Sony Demo was juddering visibly (not micro-judder, substantial judder). He first said that the default motion settings on the TV were the cause, but after a long time playing with it it improved a bit but it still didn't seem to be handling it correctly - we reduced major judder to more micro judder. Testing other content, both on his USB and on some of the apps, the motion issues replicated themselves in about 75% of content I saw.

HD upscaling wasn't as impressive as I was hoping - it was just about watchable but not great. SD upscaling was surprisingly good given it was SD content.

So, after 2 hours in an admittedly not great environment I have concluded that this is the TV to get if you are going to watch lots of 4K HDR but for HD and 4K SDR content there are better alternatives for the money, in my opinion. I spent just over 30 minutes with the B6 OLED 65 inch in Cinema screen mode watching exactly the same content (thanks to the USB!) and the picture made me go "wow", something I desperately wanted to do with the Sony but it didn't deliver. I even managed to get some things to play side by side from Youtube and iPlayer (not great sources) but it was a great test to see how the TVs handled it. The OLED impressed me much more on these tests to my eyes.

The Sony rep watched the OLED stuff with me and he said as follows:

That there were still bugs on the ZD9 which will be patched by updates in the coming weeks, this may affect the motion and some of the menus
It was running Android 6.0.1 (I checked) and that there would be an update to this to fix some issues present too.
That in terms of upscaling, the OLED may impress more with HD content (was this him admitting defeat?!) but the Sony will impress more with 4K HDR.

For £6,299, for me it has to impress more than other TVs in all types of content for me to want it.

I'm sure many of you will get great pleasure out of the TV, but it's not for me. Please do not attack me for this post - these are just my observations and my own eyes!

I feel quite disheartened and disappointed as I wanted this to be an amazing set and I really wanted a 75 inch TV. However, ultimately I want a picture which gives me great pleasure to watch day in day out, and from my time with the ZD9 it just won't do that for me.

On reflection, now re-reading the Whathifi review, I have to say my experience this afternoon tends to agree with the motion issues they highlighted.

One last point from today - the fact that the Sony reps were making all these excuses for the set I found quite disappointing.
Está claro que la Sony Bravia ZD9 es muy buena en unos puntos, pero no en otros, y lo mismo pasa con otras como las OLED, en fin, lo mismo de siempre.
