Tizen 5.5 on Studio but TV has 4.0

Hi there

Have built a (fairly simple, so far) app in Studio, where the emulator is 5.5. Only problem is, when I went to deploy to a smart tv, debugger shows that I was getting errors calling tizen.filesystem.createDirectory - saying it is not a function. This had me baffled until I noticed that the TV appears to be on Tizen 4.0 (at least, thats what I assume the Platform column in connection manager means) and those APIs were introduced in 5.0, with a lot of the older functions depricated since 5.0.

Now, I realise that depricated does not mean removed, so I could code against the older function list, but the newer functions are both more capable, and more efficient, so I’d like to be able to use them if possible.

Does the software update (https://www.samsung.com/au/support/tv-audio-video/how-to-update-your-smart-tv-to-the-latest-software) upgrade the tizen version?

The TV version is UA55NU7100
