Updated WebOS 05.70.30 TO WebOS 6

I have a 55UH6150 LG Smart TV and was wonder if it was possible to update it to version WebOS 6. I have some apps I would like to install but sadly they are only avaible on the content store from WebOS 6+. Is it in anyway possible to update the SW for it?
I know the page doesn't show WebOS 6 listed for it, but am curious if there is a way I can do it anyways

Any information would be much appreciated

05.70.30 is likely the firmware version not the WebOS version - that TV probably shipped with WebOS 3. LG dont usually update the WebOS on previous TVs - they just fix bugs. New Tvs comes with new WebOS versions. Most apps do run on all WevOS versions but some need WebOS 4 or newer.

It did ship with WebOS 3 (Figured that out after posting this). Im in the boat of an app that runs on this WebOS 3 but cannot be installed without using developer mode (Which annoyingly expires). Thanks for the answer, wasn't quite what I was hoping.
