I also purchased a tablet that was an import and knew nothing about this it was on an Samsung A54, and also found that I couldnt get Samsung Care+ when entering in my IMEI. further to this samsung stated that I may run into problems with the PlayStore as the playstore uk and india are totally different. Yes their in english because thats the settings on you device. I have also been told that the practice is illegal and they are not allowed to be selling phones meant to be sold for another country in the UK. I had a refund on my A54, and on my tab s9 ultra as It was purchased from a third party seller claiming to be a UK model but wasnt.
When registering on samsung care+ if you ever have invalid product or SKU not known in the country appear in red it is likely to be an import. Samsung checked my IMEI for the tab s9 ultra and wasnt even on their systems. Concerning get a refund
