I can't really comment on it other than I know about DataColor's devices. I had one a long time ago, but wasn't happy with the accompanying software. It didn't have a choice for D50, which is more important than it sounds.
X-Rite did a worldwide test some years ago. They recorded the color temperature of light at noon with a clear sky. The average was 5200K. But it isn't a straight 5200K. This is where D50 comes in.
If you look into it, you'll see 5200K is often presented as a photographer's monitor settings. But it also isn't correct. That makes everything 5200K, including the white and black points, even thought the true natural measurement is much closer to 5000K.
This is why using a 5000K setting also doesn't work, which is all the DataColor software I had (from at least 10 years ago) offered. Using that setting makes the entire gray balance 5000K and results in noticeably yellowish gray balance.
D50 uses a 5000K white/black point balance, but also builds a slightly cooler - yes, you guessed it - 5200K mid point gray balance. This is as close to a natural light gray color balance as you can get.
Unfortunately, even looking at the user manual PDF for the Spyder, you can't tell what choices you get. It only (repeatedly) insists the user choose 6500K as the recommended setting. Any true color professional will tell you to never use that setting. It even states this is the color of daylight at noon. This is wrong. Very, very wrong. That number comes from an old test where they measured daylight in a far northern area on a cloudy day. Yeah, of course it's going to be a cold, bluish color.
But literally anyone can disprove that claim by setting their monitor to 6500K. Follow that by taking a shot of you home or front yard on a sunny day and then display it on your computer. You will never - truly, never - see anything out your window as blue as it will look on your monitor. And you can't even adjust that blue color out since the white and black points are fixed at 6500K. Anything on that monitor will be heavily blue. Always.
