Please contact before using a code if you need to guarantee UHD and you are not sure. Google Play is the same but does sometimes redeem HD in Google Play. iTunes usually can also be UHD, but not always. The others depends on how it enters your movies anywhere account.
If by chance Fandango buys the rights to the movie it will show up in Fandango at that point, but not until then. Example is the movie Office Space is sold through VUDU, but not sold on Fandango, so it will only show up in VUDU and not Fandango, but it will be in your locker.
Same with a US code, please do not buy the US codes without being from the US or knowing how to redeem the US codes beforehand. If you are not located in that country please do not buy this code unless you know how to redeem a code from another country with a proxy. A code will state another country in the title if it is from different country than the USA, like (CANADA) or (UK).
