Long time lurker, but new member here. This thread is amazing with its detail, especially link to murtaza's spreadsheet.

I am due to fly on UAE409 from MEL-DXB in a week's time and have been watching Youtube vids on the retrofitted seats on EK. MEL was one of the earliest destinations to get the Premium Economy cabin and seems to regularly receive the A380ULR variants on this route. However what I am surprised by is that many recent first class vids (one video from 25 July 2024 - A6-EVS apparently) from MEL show the older grey leather seat with the older shorter curved door in the F cabin.

Whereas some LHR/JFK flight videos show the Champagne coloured leather seat in F.

Is there a list that captures which registrations have the newer Champagne seats vs the older grey seats in First for the PE/Special Routes aircraft?

Also what is the reason for not changing the F seats on some aircraft which have undergone PE and J class seat colour change? Or am I just wrong?
