I see that i2c operate up to 400Hz

    You might want to check if a read-multiple-bytes scenario provides enough bandwidth.

    Just add up the number of transfer cycles required, and compare it to the time frame of a 6kHz update rate.

    In SPI mode, the LSM6D allows up to 10MHz.

    With SPI everything is ok. Question is can i reach same ODR with i2c?

    So check it by doing said calculation, or an appropriat software implementation.

    Such bandwidth calculations are the SW engineering standard tasks.

    it looks that everything is ok. i will also try fifo mode to increase productivity.
