For art and photo/video work, you really need a screen with close to 100% sRGB coverage. External monitors and TVs all hit this threshold, but most laptop screens do not. The screen on the Inspiron 13 5379 you've linked scores a pathetic 60%-70% of sRGB. Colors will be pale and washed out. Totally unsuitable for graphics design work unless you're doing black and white graphics, or using an external monitor. If you try to get the color saturation "right" while editing on the laptop, they'll end up oversaturated when viewed on a TV or external monitor.

Notebookcheck has a list of laptops with the best displays. Unfortunately it's rather short (90%+ is optimal, but 80%+ is passable if you also use a desktop monitor), and most of them will be out of your price range. It's also a German site, so some of the models they review aren't available in the U.S.

The best advice I can give you is to search for reviews of the models you're considering with "sRGB" and/or "Adobe RGB" added as search terms. You should look for something 90%-100% sRGB (about 68%-75% Adobe RGB), with an IPS-type screen (IPS, PLS, AHVA) so the colors don't shift as you tilt the screen. A TN panel is an immediate disqualification. If you also take photos with a DSLR, you may want to consider a screen with close to 100% Adobe RGB, although that adds a lot more expense and new complications when using the laptop for non-art/photo work.
The "safest" (but not cheapest) choice is a Macbook Pro. Apple specifically caters to the artist and photo/video market, so puts 100% sRGB screens in them and calibrates them at the factory. However, as you say your primary machine is a desktop, you will probably want to get a colorimeter to calibrate your desktop and laptop screens (the Spyder is a popular low-cost choice). So factory calibration would be irrelevant. There's also the problem of your software licenses. Adobe is pretty generous and lets you use one license for both your desktop and laptop (install the software twice), but they must both be PC or Mac, can't have one PC and one Mac. I dunno the licensing situation with Creative Commons as I don't use that.
