That's the mock suede alcantara seats, the base part.
https://en.wikipedia.org/wiki/Alcantara_(material)
Velor is mock velvet. Seat in international markets positions alcantara above cloth, but lower than leather.
The dealer who knew I didn't like leather was trying to get me to agree that the demo LHD car they had in alcantara felt "funny". It felt OK to me

. The Xcellence in other markets gives you options, just in black leather for the UK. IRL you can have brown or black leather.
Running through the Spanish configurator for the Xcellence "Azul Mediterráneo" blue is free (non metallic) whilst Azul Lava is extra. Could have been the other blue in the video may be ?. Looking at the video again it is metalic but the guy has a funny complexion, he's looking very orange (trump orange), assuming it's not a spray tan the colour balance isn't right on the video hence why the car isn't the right colour. They haven't set the white balance on the camera.
Then you get two choices of the seat materials Alcántara or Tapicería en piel (leather), then two colour choices for each Alcántara Tapicería or in ***** and leather Tapicería de piel en color marrón (brown) and black leather. So for Xcellence we get enforced black leather in the UK, Eire gets the choice of black or brown leather. That's to say we have our choice cut back by 75 percent, Ireland 50 percent. Whilst I suspect without checking all other major European countries get the same choice as Spain. The video was Italian BTW. The orange seats features a lot, that's all I've seen in the two demo cars in the UK, but they aren't in the UK spec for the Xcellance but just over here for demonstration purposes.
In one early Youtube video at the original launch in Spain I saw the leather falling apart on the car... it was on the back of the front seat viewed from the rear. Hopefully they will have that sorted on the production cars.
