This is true. And it was the main reason I was preparing to upgrade my 2013 T5. But as LED dash isn't an option (why not?!) I think I'll keep my T5 for another few years and wait for the T7.Its looking like the 6.1 panel van has no option for LED dash, only Cali's.
The dash is the same as a T Roc and Polo 2g, I have 2 of those and try to fix itQuite a few have done it on Golf R 7.5 virtual cockpit into a 7R. Lots about the electronics and coding on the VWROC forum.
Golf 7 & 7.5 dashes are the same shape. Geneva photos of the T6.1 looked like the dash itself was a different shape though.
