for an easy to play file on the TV, I normally de interlace and export as .mp4 which I use Davinci resolve which likes working with Apple ProRes.
I could capture it as uncompressed 8 or 10 bit, but I didn't think it was necessary considering the compressed nature of DV?

Some mixed-up concepts here...
uncompressed 4:2:2 = no data compression, no colorspace compression
DV = 5x+ data compression, 4:1:1 NTSC or 4:2:0 colorspace compression. The video artifacts are blocks, and NTSC has 50% destroyed/lost colors (replaced by smears, grays, and hue/tint shifted colors).
VHS is far less than 10-bit, not even 8-bit. In analog>digital equivalency, VHS is like 6-bit dithered color, which you'd often find on budget computer monitors (including IPS displays). It's quite decent bit depth, but with detectable flaws in gradients.
ProRes LT and proxy are somewhat compressed, and don't react well to VHS noise. HQ is better. The main difference is the bitrate. VHS is noise, and noise needs more bits to not artifact.
Got all that?
