help. LG CX OLED Chromatic Aberration, and color shift for PC viewing distance

How to eliminate the CA?
It's really bugging me when I'm doing design work on photoshop. Currently already using RGB 8 bit. Maybe i need 10bit? Already ordered HDMI 2.1 cable, will test it after it arrived. Dunno GTX 1660S supports HDMI 2.1 or not tho.

also how to reduce the color shift for PC viewing distance? around 8" area dead center is fine, but the closer its to screen edge, the more the color shift. If I sit further away, it's totally gone.

other issues like screen shift, DSE on dark gray, and its refusal to save the "universal remote" to work with my ancient surround sound system across TV reboots didn't really bother me. But these color shift and CA keeps bugging me every day.

admittedly it's only been 2 days, so probably I'll get accustomed to the color shift. But the CA is really bugging me and making me do double-take on my designs. (huh, what's this stray line? zooomed in.... oh it the OLED CA)
