Removing DeHalo_Alpha artifacts


I'm trying to restore an old DVD which has a lot of grain, dct artifacts and a really strong halo. This is my current avs script:

knlmeanscl(D=8, A=5, h=3, device_type="GPU")
DeHalo_Alpha(rx=3.0, ry=3.0, darkstr=0.4, brightstr=1, lowsens=50, highsens=50, ss=1.5)
GradFun3(thr=1.5, radius=6, mask=2, mode=0, smode=0, debug=0, lsb=False, lsb_in=False, staticnoise=False, y=3, u=3, v=3)
I'm satisfied with the grain removal (but you can recommend something better instead of knlmeanscl), the GradFun3() is maybe a little bit too strong and needs some tweaking. But the dehalo is just not that great so far. The strong white halo is now replaced with a slighty darker color than it should be. brightstr is 1 as you can see in the code, 0.8 is the recommended value for anime and cartoon but it seems that it does not do anything if I try something lower than 1. Could you guys recommend something to fix this? Or maybe another dehalo filter? I tried HaloBuster() but I couldn't get it to work.

Here's the comparison: https://testfra.me/0s/
