PAPIs
Thanks for linking these pictures - I like the last one! That must have been some wide angle lens.
Don't forget that your PC screen may have been set up so that it is biased towards certain colours and, being a CVD, you may not notice this. It is therefore a bit hit and miss to say that you won't be able to see the colours on the new test. In a real aircraft they stick out to me like nothing else.
Two points:
1. The runway shape provides more clues than the PAPIs during the day. At night it is a different story but the lights at the side of the runway still provide a massive clue to the aircraft's position relative to the glideslope of the runway in front.
2. Some of the pilots that I know would have trouble even seeing the lights on a PC screen let alone in the cockpit as they are facing another challenge of the 6/4 in each eye kind. These pilots are a mixture of military, commercial and private.
Let's hope this new test is a winner and is adopted by the CAA as quick as possible. It could be the start of a practical assessment of a person's ability to fly and interpret information rather than reliance upon outdated medical tests.
