It is worse, using algorhythms to "borrow" neigbor subpixel to correct for a lower effective resolution is not a "feature" it´s a bug which they try to fix with it, same method can be used on an LCD screen, but isn´t needed for obvios reasons.
OLEDs have 2/3 of the resolution of an LCD. - (A pixel on an OLED has 2 subpixels)
OLEDs throw away half of the red and half of blue color information they get.*
An OLED is only able to represent green pictures in it´s full resolution, where using red or blue pictures throws away half of the resolution. Thats why OLED screens have this shimmering effect with reading text, and it looks so awkward in VR, where same VR-HMDs with same resolution with an LCD look far superior.
Only people with tritanopia wouldn´t be able to distuingish an OLED from an LCD in terms of resolution.
*hardware wise, of cource you could use software to correct some problems with it, but software won´t be able to compansate for the missing subpixel so that the resolution would equal to an lcd.
also I didn´t forgot that RGB has 33% 33% 33% as this the whole base of the whole argumentation and calculation, why I divide/multiply by 3 for LCD. You seem to have forgotten that an OLED ISN´T RGB, but RGBG, which makes 50% Green 25% Red and 25% Blue. To get back to RGB you could therefore only use 25% G, 25 % B, 25% R - which is the reason you would throw 25% of the green subpixel, as they are only useful in representing green.
Just to be clear, I firmly believe that OLED panels have alot of very useful benefits which LCDs dont provide, but they lose clearly when it comes to resolution.
