I suspect the major difference may be the EX90 will not offer a leather interior like the Polestar 3. If that is the case, the video is serving the purpose of helping the buyer view a non-leather interior as being premium. The key may be linking the materials to Scandinavian design. Although the typical EX90 buyer might be able to afford a luxury vehicle, they might also be seeking a way to stretch their buying dollars and stay within the US cap of $80,000 for an SUV to obtain the rebate. (We know the Polestar 3 leather interior will cost $5,500.00.)
