"After some further testing the black glow is fixed with 05.30.25. Hdr game mode is just like before. The menus are so laggy, especially when input is in 4k or hdr. They were perfect in the 04 firmware, incredibly that LG has not done properly testing. Be aware, you can not downgrade after updating to 05.30.25, and this is how it will be from now on. Lg has blocked the ability to do this."
