Intended to dismiss or invalidate any other experiences so I apologise if that was how my post was perceived and for the apparent rudeness (also not intended).
My *intent* was to clarify from a side-by-side comparison of the Series 4 & Series 5 (literally side-by-side on two watches) that the brightness was definitely dimmer on the Series 5 but to also provide my experience with this in case the issue was limited to the displays/ambient light sensors on some specific watches rather than an issue with the Series 5 in general. This is why I stated twice in my post that my comments were opinion and personal anecdotes which, in hindsight, was insufficient clarification. Please accept my apologies - obviously tone and context are difficult to read in text.
