Yes. Simplicity and function over form. 90s buttons looked like buttons, for instance. And theming was a simple matter of changing your fonts and colors. Windows 95 didn't need a special 'dark mode' supported by the OS, because you just changed your colors in the GUI tool for changing colors and fonts and you were done. Modern GUIs are ridiculous and stupid and overcomplicated. Much like most of modern computing.
You're over-romanticizing the past. There were plenty of apps even in the Windows 95 era that drew their own widgets and only half-respected the colors you set in the control panel, and that consequently looked like pureed ass if you changed the colors from the default.
