In the PCN image the sign does not appear to be sufficiently illuminated and visibility seems poor.
The July 2022 GSV images of advance warning signs present the driver with a conflicting situation:

In terms of challenging the PCN (and the one from your corresponding post as well) both in the same area.
You could park at the nearby Aldi, then on foot walk to the restriction, before the advance warning sign and just video your approach to the advance warning on foot to provide perspective after dark. You may need to cross road to obtain the view of the restriction. You can then include this in your representation to the LA for them to consider. It's important you upload the video to youtube as unlisted link-access only at zero views, so only the LA can view the evidence, you would include a link in your representation. If they send a Notice of Rejection, you can check if the view count increased or not. If not then you have a failure to consider. There are other points you can challenge. I responded to your other post.
Perhaps read this case where the poster included a video in the first link.
