Several Apple Watch series 4 customers complain of a strong off-angle blue tint

Apple recently launched its latest smartwatch - the Watch Series 4. It seems that at least some customers are complaining about a strong blue off-angle blue tint on the new OLED display. Some of these customers say that the tint is stronger compared to previous generation Watch devices - and also stronger than the tint on the iPhone X and LG OLED TVs.

It's not clear whether this is a real issue or not at this stage - we only have heard of a few customers complaining so far. But this is interesting as Apple has adopted its new LTPO backplane technology in the Watch 4, which could be responsible for the stronger tint (Is this the beginning of LTPO-gate?). All previous Watch devices used flexible AMOLED displays made by LG Display. We do not know yet whether LGD is still the exclusive supplier, or whether Apple added Samsung Display as its second source (or even exclusive).

The Watch Series 4 has a larger AMOLED display compared to the previous Watches - 1.78" 448x363 on the 44 mm watch and a 1.57" 394x324 one on the 40 mm model.
