The Play Store is getting this major feature at last

Some Android 10 users were in for a surprise when they discovered a setting for the Play Store that activated dark mode, a long-requested feature.
Don’t get your hopes up too soon—this isn’t officially out yet. However, as Android Police spotted, some users did find the setting for dark mode in their Play Store app. Though Android 10’s system-wide dark mode works well, Play Store is one of the few major Google apps left not to offer app-specific support for a dark theme.
Though the feature seems to appear at random without regard to the app version, it only seems to be available on Android 10 devices. Support for Pie and older is still unknown, though it possibly might only make an appearance on devices with the newer operating system. We’ll just have to wait and see.
