and my hdr movies arent washed out anymore on my 1080p plasma

But there weren't any fixes for that.  

Yes, they did change something, as I noticed a difference as well. 

HDR content is not completely washed out anymore when played on a non-HDR TV. 
That said, I'd say it's got a ways to go before being comparable to the non-HDR version of the same content. 

It becomes very obvious if you have 2 copies (one HDR and one not) of a film and check them back to back in Kodi. 

I was checking out my 4K HDR copy of Deadpool 2 and then immediately switched over to a 1080p blu-ray copy of the film and checked the same scenes. You can definitely tell the colours are still a lot better looking in the 1080p copy.
