TV is awesome, improved in everything I hoped for. Android and menus are so much faster and smoother, a real joy to use, quick settings are so usefull, remote awesome, much better experience with it, more responsive and so much nicer, better layout of buttons.
Picture is improved aswell, out of the box the picture is a bit too green for me, it's funny XF is greener then XE and XG is even greener then XF but it behaves differently, I set greens -4 and it looks amazing now, if I do this on XE or XF they look to red or pink in some scenes but XG does not, it looks stunning, is has a better colour consistency. Skin tones are nicer then on both XE and XF, less green.
Blacks look even deeper with a bit better shadow detail then on XF, shadow detail is similar as on XE but picture looks deeper then on both TV's. I also did a test of black uniformity, disabled local dimming, blacks are deeper and more uniform without local diming on XG, I had two ugly spots on XF that annoyed me but on XG there are only very mild spots and you never see them when watching movies even without local dimming while on XF I could see this two spots during day especially in netflix and android but on XG I can't see any bleeding in this two.
Motion seems better even though the settings are more limited, if you put the smoothness at max it's butter smoot no hick ups like on XE and XF, maybe that's because of faster processing, it also has less artefacts.
Viewing angle seems to be a bit better aswell even though the picture turns more green as on XF which I'm not a fan of but I dont watch fron angle so it doesn't really matter.
Ultimate processor doesn't seem to be a big improvement over extreme as some people say, there is barely any difference in any content both are supperb.
Dolby visions and HDR, yes, this is what I hoped for, better DV and HDR, my god, I'm so much more happy with this two, it has so much more shadow detail, nicer colours and three presets for DV, DV dark, bright and Vivid, so cool and guess what the subtitles are so much more dimmer then on XF wich were killing my eyes. All white stuff on netflix like play, pause icons everything is so bright on XF while on XG it's not, it's even dimmer then on XE and because of this there is no blooming when this icons appear, so awesome, even if you set the picture on XG like 50% brighter then on XF the subtitles are still dimmer on XG, love it, they don't distract you. On XF something is wrong, menus in netlifx, subtitles everything is so much brighter then movies while on XG they are the same brightness, the brightness on XG is just much more constant while on XF somethings are so much brighter then other, XE is also better in this regard but Xg even better.
XG is a better TV in nearly everything, I'm so glad I went for it, it was absolutely worth the extra 130€ , I would play even 300€ more for it, XF is going straight back there is no contest.
