15 year old shoes, normal care, natural discoloration

The leather has turned mottled just through age. I haven’t done anything to it apart from using neutral cream to keep the leather from drying and give it a shine. I wore it every day for the first 5 years, the heels are semi-worn away, so I only wear them about once a week now.

I actually quite like the mottled effect, the scars on the toes, and the scuffs on the heels. Is this good patina, or just horrible discoloration?
