Using vim-solarized8 in vim works when just using powershell, but screws up when using ConEmu and powershell

[CMCDragonkai]

Basically my vim is using:

" Consider the background as dark
set background=dark

" Choose the colour scheme
set t_Co=256
set termguicolors
colorscheme solarized8_high

And the theme from https://github.com/lifepillar/vim-solarized8

So when I use it raw powershell, it works nicely. However if I launch powershell from conemu and do the same thing (note that conemu was stock with setting color scheme <Solarized>.

Versions

ConEmu build: 191012 x64 OS version: Version 10.0.18363 Build 18363 x64 Used shell version (Far Manager, git-bash, cmd, powershell, cygwin, whatever): powershell 5.1.18362.628

I have the same issue. If I disable termguicolors ConEmu works well but colorscheme plugins don't work.
