I think it is because most of the image processing software manipulates in 24 bit. There is a section in the scanner software that allows you to adjust this conversion. This vuesmart software may just be adjusting the conversion phase. I also have the Photosmart scanner, but was tired of having to adjust the crop marks to do full frame scans. The scans were also a little low in contrast and poor in shadow detail. I just got the Canon and it seems to be scanning the slides a little too dark if you do not adjust for each scan. It does negatives fine, but I don't use colour negative film. I think the flaw with all these scanners are they are aimed at the home market and assume you will be scanning prints and negatives which will later be printed with an inkjet. This is the problem with the HP and its defaulting either to the cropping for standard print sizes or standard web sizes. I could not make a custom size that would save as a default at 1200 dpi. In the case of the Canon, it needs some optimization for slides. It seems to have some optimization for colour negatives since you can select the emulsion type or let it select automatically. When you set it for slides, there is no option for emulsion types. I will work out the brightness problems with the Canon as it seems to scan with more contrast and sharper images. This scanner is very well priced as well. It was around $980.00 CDN which is $675.00 USD.
