2018 Niro Hybrid Premium at 130k km (81k miles) - buying from a dealer, is the mileage a concern?

Looking at a 2018 Kia Niro 1.6 GDi Hybrid (Premium trim, DCT6) in France. About €14,500 all-in, buying from a large reconditioning dealer with 12-month warranty and a 30-day money-back return.

The car:

• 130,430 km (~81,000 miles)
• One private owner for the last 4 years, company/lease car before that
• Fresh inspection passed with zero faults, emissions perfect (lambda 1.002)
• History report clean — no accidents, no import, no odometer inconsistencies
• Recon included service, oil change, front tyres

The mileage breakdown is what interests me:

• 2018–2022 (company car): only 43,000 km
• 2022–2026 (private owner): 87,500 km, steady ~21,500 km/year

My questions:

1. Is 130k km a lot for this powertrain, or is it still early days? My understanding is the 1.6 GDi Atkinson has a timing chain and the hybrid system takes load off the engine.
2. Main concern: the DCT6 clutch. What's the realistic lifespan, and does highway-heavy use genuinely help? Any symptoms I should watch for during the 30-day return window?
3. Anything else that typically goes wrong on these around 130–180k km? I'd rather know now than find out later.
4. How's the hybrid battery holding up on high-mileage Niros of this generation?

Planning to keep it 4–5 years, family car with a toddler. Thanks.
