OK, thanks for all the comments.
First of all let me stress my comments were NOT intended as "grumbles" - they were merely my thoughts having viewed the video and being amazed at the perceived disparity between the 2 halves of the footage.
There seems to be the suggestion that I need a 4k monitor counterbalanced by one that says the majority don't even use 1080? I have no idea what screen resolution "most people" use - I chose a 32" 1440p as it seemed the best compromise between size, text legibility, video quality and value for money in my particular environment.
I do not understand why the particular handling characteristics of YouTube has seemed to "downgrade" one half of the video over the other, at least on my system. Although someone else told me that on their 1080p monitor there seemed little difference between the two? So obviously it becomes very difficult to judge the ACTUAL video quality, sharpness and detail etc. when there are so many variables in effect. I assume any tweaks should only be done by assessing the raw footage direct when displayed on a monitor with a resolution equal to or better than the video resolution.
All I can say say is the A119 V2 gives extremely pleasing results especially with the excellent 6Ro firmware, but I definitely think it could be even better with less sharpening applied.
