You can buy the UK Skywalker set for 65 GBP and have the 2019 SE without any 4K discs.
Do you have a link to such a set, please?
Because if the tweet by SWVC (doubleofive) is correct:-
‘Confirmed by @thedigitalbits that if you buy the Blu-ray-only set you get 11SE on Blu-ray, but if you buy the UHD / Blu-ray combo set you get the 19SE on Blu-ray. Because that’s not confusing to consumers.’
Then you have to buy the UHD / blu ray combo box set to get the 2019 Disney+ SE version.
And that if you buy this blu ray only set below, then you will be getting the 2011 SE version:-

Or I have gotten this wrong?
